An American Children's Game show created by Artur Spigel and Michael Chaves and hosted by Graham Conway and Devon Deshaun Stewart. The show focuses on three child or pre-teen contestants competing each other. The First round is an obstacle course called The Megalator in which the three contestants must completed the course in the fastest time they can, the two contestant with the least time will move on to the next round while the contestant with the most time is eliminated. During this round, the hosts checks on Master Mayhem to see what's he's up to and sees which monster he's going to send to Earth.
The second round, The Mega Duel, sends the two contestant to a planet, chosen by Master Mayhem himself. If one of them has the most points will be through to the next round.
In the third round, The Monster Mashdown, Master Mayhem then sends his monster of the episode to a fictional city, Mega City. The contestant warps to a secret bunker where he/she will choose one of the four armors (the Mega tank suit, the Mega Ice Suit, the Mega Money Suit and the Mega Hammer Suit), once gear up, they pressed a button on their wrist and grows 600 ft. tall. He/she must find three powers pods inside buildings (two while using the Mega Tank suit) in order to activate the Mega Laser to zap the monster. Another pod is also hidden in the buildings; if found and used, it will activate Mayhem Time, in which a rival monster will fight the opponent for 20 seconds. Every power pod scores some money for the contestant but if he/she throws a boom building the money they earn will reset to zero until another power pod if found. If all the power pods are found, The Mega Laser is activated and the monster is defeated, if the contestant runs out of time, they have to sacrifice themselves in the Chamber of Doom in order to save the Earth. Win or not, depending how much points he/she got, he/she can still go home with a few cash.
Throughout the show, a Sub-Plot resolves around Master Mayhem and his monsters in a space condo on a unknown planet, depending on what title of the episode is called. Said subplot involves the day-to-day sitcom shenanigans Master Mayhem and his monsters get up to.
Massive Monster Mayhem provides examples of:
- Alliterative Title: Massive Monster Mayhem, or MMM for short.
- Animate Inanimate Object: Dome Diddy Dome is a variation; any object placed in its head-dome will gain sapience, take control of Dome Diddy Dome's body and wreak revenge on the species that created it.
- Attack of the 50-Foot Whatever:
- In the final round, Master Mayhem sends his chosen monster to earth to wreak havoc. The contestant becomes a giant with the armor of his/her choice to try and stop the monster.
- Master Mayhem eventually travels to Earth to take matters into his own hands.
- Behemoth Battle: It's a Monster versus a very, very large child. And sometimes, monster versus monster too, as they have plenty rivalries.
- Berserk Button:
- Never annoy Eye Eye Eye, especially if you're a Doo Doo Doom's member. Macho Cheese learns this, after telling a joke around her, during her introduction.Macho Cheese: OK, What do you say to a three-headed monster destroying your planet?
[Eye Eye Eye then kicks Macho Cheese from behind, sending him flying]
Macho Cheese: EYE EYE EYE!
Eye Eye Eye: That's my name, don't wear it out.
- Also, never cancel a date with Dome Diddy Dome while it has a phone for a brain.
- Never annoy Eye Eye Eye, especially if you're a Doo Doo Doom's member. Macho Cheese learns this, after telling a joke around her, during her introduction.
- Boomerang Comeback: Major Disappointment's intro sequence includes the giant robot pulling out his boomerang-shaped brow and throwing it at a building, only to get hit in the face by the return.
- Master Mayhem has a couple, "People of Earth -Insert Plot-" and the most common, "What the Wormhole!"
- Macho Cheese's "Hey-oh!"
- The Comically Serious: Eye Eye Eye to a point; she may as well have crawled out of an episode of Power Rangers.
- Covered in Gunge: The fate of the contestants who fail the Monster Mashdown, and have to make a sacrifice in the Chamber of Doom. They end up covered in electrified purple goo.
- Excited Kids' Show Host: Host duo, Graham and Devon.
- Genki Girl: Me-ouch.
- Heroic Sacrifice: If the time runs out in the final round, The Champion will be sent to Chamber of Doom, where they'll be sprayed with electrified goo.
- Homage: The entire series is one to Japanese Tokusatsu shows such as Super Sentai, Kamen Rider, and the Ultra Series, plus movies of this ilk such as Godzilla and Gamera.
- Hurt Foot Hop: While exercising with Robro, Master Mayhem drops halters on his foot and clumsily hops around.
- Inconvenient Summons: The Clip Show episode starts out with the monsters using their teleportation beam on the two hosts, who show up in pajamas and brushing their teeth. The stay in pajamas for the whole episode (although they were still wearing their headsets).
- Joke Character: Major Disappointment has all the trappings of one, with the lowest Mayhem Rating, a complete failure to live up to his family legacy of unspeakable destructive power, the given name Melvin, and bunny slippers.
- Kaiju: The Game Show. All about a villain sending giant monsters to Earth, and the contestants gearing up before increasing to comparable size for a final confrontation in the city, which is as much about smashing buildings than actually fighting.
- Laughably Evil: Neither Master Mayhem nor his monsters are menacing in the slightest, in keeping with the series being a love letter to Japanese Tokusatsu shows.
- Manchild: The monsters are incredibly childish.
- Masked Luchador: Macho Cheese.
- Not So Above It All: Despite being the most serious of the monsters, Eye Eye Eye is a bit of a fish out of water; she thinks her high-pitched battle cry would succeed as a pop song and was once tricked into thinking an empty pizza box was a sacred contract.
- Not-So-Harmless Villain: Despite their pettiness, they are rather competent in keeping the Earth in the line of fire.
- People in Rubber Suits: Master Mayhem and his Monsters.
- Proud Warrior Race Guy: Or Proud Warrior Race Gal — Eye Eye Eye.
- Real Name as an Alias: Melvin, Major Disappointment's real name.
- The Rival: During The Monster Mashdown, upon activating the Mayhem Pod, it summons the monster's rival to briefly battle the monster. The rival pairs are Eye Eye Eye and Dome Diddy Dome, Macho Cheese and both Me-Ouch and Robro, and Robro and Teensy; Teensy also attacks Macho Cheese and Major Disappointment. At one point, Major Disappointment gets up off his butt and attacks Teensy. The best-known rivals are Robro and Teensy the Tri-terror-tops; there are several reasons why they have been long-term rivals.
- Running Gag:
- Every cold-opening of the series has Master Mayhem telling everyone on Earth about his latest plan.
- In the first round, the hosts give a different origin for the Megalator in each episode.
- The Mayor and an Ice Cream Truck getting crushed by Master Mayhem's Monsters.
- In the preparation of the Monster Mashdown, after the Champion grows to 600 feet, Graham happily says that it worked, and he mostly says that he/she didn't explode like the last one and stating to the Champion not to blow it.
- Show Within a Show:
- Teensy Time, an educational children show, hosted by Teensy the Tri-Terror-Tops. One of these episode had his rival Robro as guest star, but he ended up wreaking the set after he fails to smash a model tower.
- One episode features a sitcom starring Master Mayhem and Major Disappointment.
- Master Mayhem once appeared on an in-universe reality show.
- Single-Biome Planet: Uncle-arctica and Planet Waaahhh!
- Successful Sibling Syndrome: Master Mayhem's relationship with his brother Carl.
- Temper-Ceratops: Teensy the Tri-terror-tops, a humanoid Kaiju based on the triceratops. Although Teensy's high-pitched voice and children show host side job dilute a bit the terror.
- The Thing That Would Not Leave: The sitcom episode turns into this when Major Disappointment initially refuses to take the opportunity to try to defeat a human hero and impress his parents so he can move back home and stop being Master Mayhem's infuriating roommate.
- Visible Boom Mic: One episode has a filming crew interviewing the monsters, with the usual boom mic antics, including Master Mayhem repeatedly bumping into it.
- Vocal Dissonance: Teensy has a high-pitched voice. Fine for a children show host, not so much for a massive monster threatening to destroy the Earth.
